to add on jonnykanoo's bit about the journal ...
i find it quite useful to take a screenshot of a chart from each day i trade and mark my entires and exits ( also whatever pertinent info regarding the trade ) that way i can see what i did and didnīt do, see etc ....
like maybe i was right about direction but entered too early and had to "suffer" a bit of red pips before it went my way ....
or the trade that was positive but slowly turned negative because i thought it was a minor correction and was hanging on to "let my profits run "
or that time i bought at the top , sold at the bottom ...
there is so many little glitches we experience as we are learning ... having a visual reference of each trade is wonderful ....
i can't lie though , reviewing your losing trades will sting ( at first) , but since iīve been doing the screenshot thing , my trading has improved tremendously and my stupid mistakes are much less ...
a screenshot of a "bad trade" is a much better teacher than a screenshot of a "good trade " where everything went your way .....
hope this helps save you a bit of "tuition"
